Progress

As cast with minor port matching done by DAP (Diesel Auto Proformance) the manufacturer.

Ported and blended

With 6 EGT probes installed/ mocked up and ready for paint iwith 2000° ceramic paint, wrap it up with double thick exhaust wrap from all-purpose pipes and put it on. I decided that installing the individual EGT probes would work in the manifold side of the gasket with the new manifold due to aftermarket design changes/improvements leaving room with exception of #4 it sits slightlw deeper and at an off angle still centered but ~ 1/3" farther from the valve.
The test showed that 4 years with the ceramic paint and wrap produced no rust or any indication that four layers of wrap had any negative effects . Paint was intact with no thermal shock cracks or flaking. That changed when I didnt rewrap after installing the Holset HX35W12. I was washing the engine bay down forgetting the manifold wasnt wraped and @about 300° the ceramic paint started poping off like popcorn. Lesson learned ceramic paint is pointless unless wrapped on headers as Road spray will compromise the ceramic paint through thermal shock.
Preliminary install of the gage and 4 probes .
1 EGT in the standered exhaust manifold location.
1 in the in the elbow attached/part of the turbocharger 75-104 @idle 170° @10psi @700° EGT 321° @25psi @ 850° EGT
1 intake horn above tbe Grid heater. 0-70° above ambant
1 in radator core right next to the inlet behind grill block (cardbord between rad support and rad full width blocking the upper 1/3 above the IC flow path . Shows the cycling of the thermostat. Its why I got the gage /test rig, to do some testing and compairisons of the effects of modds.
Hopefully I'll be able to get it in before the trip down to Moab, ut for the 240 endurance race, next week.
